Hello all,

I recently won an auction on a MTX3 which came with a Nova motor and that's all the seller knew about it.

Is there anyway I can identify it? It looks like it might need a new bearing and I'd also like to have a spare piston and sleeve but I’m taking the assumption that I need to know the model..

Is there any markings or ways I can try to identify what motor I have? Some local track racers say that it was the stock motor that came with the Mugen kit. I’m seriously lost here.

Any help would be well appreciated. Thanks!

Rudy

Looks like it's the Mugen X12, can you post a picture of it

sure when I get home from work

xyvern,

http://deznuts05.no-ip.org/mtx3/ebay%20015.jpg thats the only pic I have. The actual motor and car is with my friend.

oh and the pic is huge so it might take some time

Based on the picture you provided it looks like this engine

thanks! I know having just one pic is kinda hard to really identify what it is but in the case of piston and sleve purchasing if I get any of the .12 motor p/s replacement kits could I go wrong?

That is the MT12 that came with the Mugen MST1 stadium truck. That MT12 has the large cooling head. The header came with the kit too.

I have a "new" TOP Novarossi TN12S1 engine, I believe it was manufactured in 2002. The specs on the engine look like a current model, except it has a standard head. The description says this is a great off-road engine. If I replace the head with a turbo head will it then be a great on-road engine? Are there differences in the timing that I will notice if I put this in an on-road car?
